Quick clearance test.

<p>Based on a great idea of J Jake 3D <a href="https://www.prusaprinters.org/prints/127569-s-shaped-tolerance-test-01-04mm-in-002mm-increment">https://www.prusaprinters.org/prints/127569-s-shaped-tolerance-test-01-04mm-in-002mm-increment</a> I upped the challenge such taht the test also includes layer and line changes and thus zits will show up as fused points.<br><br>Start with printing J Jake 3D's test as its way quicker to print, when your tuning is such that 0.1 mm is achievable this is the next level challenge.</p><h3>print settings:</h3><ul><li>0.2 mm layer height</li><li>0.4 mm outer layer width</li><li>0.45 mm inner layer width</li></ul><p>other settings as per your typical print settings.</p><h3>My learnings how to improve clearance:</h3><ul><li>Properly tune Pressure/Linear Advance. This is probably the setting reducing the zits the most.</li><li>Your filament flow has to be tuned properly, any over-extrusion will close the gaps. I set outer layers to under-extrude 5% and inner layers to over-extrude 2% to achieve the best accuracy, esthetics and strength compromise.</li><li>Retraction may be set ~20% higher than the minimum outcome of retraction tests (http://retractioncalibration.com is my favorite retraction test).</li></ul><h5>Next challenge: https://www.prusaprinters.org/prints/129499-clearance-test-a-new-challenge-who-unlocks-the-006</h5>
